At the Energy Department's Pacific Northwest National Laboratory (PNNL), researchers are using two modular homes to test energy-efficient products and calculate their energy savings. Researchers test new technologies in the Experimental home (pictured above), while the Baseline home (not pictured) serves as a control and doesn’t get changed during any of the experiments. | Photo courtesy of PNNL.

In 1958, Argonne National Laboratory began the construction of several zero-power reactors (ZPRs), which are nuclear fission reactors that don't actually generate any power. Scientists developed ZPRs to assess the performance of various reactor core configurations before actually building a full nuclear reactor. A series of ZPRs were built leading up to the construction of the Experimental Breeder Reactor-II, a sodium-cooled fast reactor power plant.

This past summer, Sandia National Laboratories hosted the 2013 Robot Rodeo – a 10-event technical challenge that determines the best robot designs for diffusing dangerous situations. The rodeo is a free event that usually includes entries from police departments and military bases in nearby states.
 
By developing these technologies, robots could potentially remove the danger to humans from the first response to unknown or dangerous situations. Challenges typically include diffusing a trip wire or boring a hole through a wall to peer through with an electronic eye.
